Abstract

BACKGROUND: Fat grafting is widely utilized in reconstructive and esthetic plastic surgery, typically with minimal complications. Nevertheless, the occurrence of fat necrosis is dependent on the technique used for fat extraction, tissue processing and the volume of the graft. The longevity of the graft critically depends on the presence of adipose-derived stromal cells (ADSC) and their promotion of a reconstituted vascular supply. OBJECTIVE: This study seeks to determine whether there are differences in 13 angiogenesis-related adipokines based on their grouping by vascular endothelial growth factor (VEGF) expression levels. METHODS: The expression of 14 adipokines related to angiogenesis in 12 cultured ADSCs was evaluated using Human Adipokine Profiler kits, which simultaneously detect 58 mediators. Adipokines of the high and low VEGF expression groups were evaluated for their expression of the remaining 13 angiogenic proteins. RESULTS: We were able to show that there are significant differences in VEGF and VEGF ADSCs regarding fibroblast growth factor 19 (p = 0.043) and insulin like growth factor binding protein 3 (p = 0.028). Furthermore, ADSCs with differentially highly expressed VEGF show a different pattern in the amount of protein levels regarding the 13 other adipokines observed. CONCLUSION: The VEGF has been described as a key angiogenic factor in fat grafts that may be linked to successful grafting; however, two of the fat samples analyzed exhibited high expression of VEGF but lacked significant co-expression of a range of other angiogenic factors. Thus, the assessment of the expression of predisposing mediators for graft angiogenesis for wound healing or contouring should include further angiogenesis promoters aside VEGF as parameters.
